Read the passage and answer the questions.
My name is Nora and I live in Sweden. I live in a small village in the mountains. I love mountains and I can't imagine my life without them. I live with my parents and my little sister. She is six and I am eleven.
My mum's name is Helen and my dad's name is Nick. My mum is a fitness coach at my school and my dad is a farmer. We have a small milk farm. That's why I am fond of sports and animals.
I get up at 6.30 and do my morning training together with my mum. Then I wake my sister up. We have a big breakfast and our mum takes us to school by her car.
After lessons I stay at school to practice basketball. It's my favourite sport. At that time my sister trains at the singing club. After that I go home with my sister by bus because my mum has some evening trainings.
After school I like to help my dad to take care of calves. They are so nice! In the evening I like reading books or going out with my friends. We are crazy about riding bikes at the weekend. I have got a cool green bike. I think I am the best bike rider because I go in for sports every day.
What is her sister’s hobby?
